7 Removing Inlet Air Thermistor
a. The inlet air thermistor is clamped with one (1) plastic band (B) to the resin component for fixing the thermistor
inserted into the sub heat exchanger fins. Remove the plastic band to remove the thermistor.
b. When attaching the inlet air thermistor, attach it to the resin component with the plastic band in the reverse procedure.
Take care during the work so that the wiring for the thermistor will not come into contact with metal edges of fins or
side plates of the heat exchanger.
c. After attaching the thermistor, clamp the wiring for the expansion valve, freeze protection thermistor, gas pipe
thermistor and suction air thermistor with one (1) plastic band.
Place the wiring for the thermistors (for inlet air, gas pipe and freeze protection),
and the expansion valve coil into the electriacal box from the wiring outlet at the upper side.
(The wiring for the expansion valve coil is not included when using the unit without expansion valve)
Fix the inlet air thermistor with the plastic band
so that the thermistor wire will not be loosened.
